.bedstead NrTnn STATES PATENT. @Tirreno J. B. MCOLANATHAN, OF EIORICON, WISCONSIN.

Speciiieation forming part of Letters Patent No. 52,585. dated February 13, 1866.

To all 'whom it may concern Be it known that I, J. B. MCCLANATHAN, of Horicon, in the county ot' Dodge and State ot' Wisconsin, have invented a new and Improved Spring-Bedstead; and I do hereby declare that the following is a full, clear, and exact description thereof', which will enable others skilled in the art to make and use the same, reference being had to the accompanying drawings, forming` part ot' this specification, in which- Figure l is a longitudinal-section of a bedstead with my invention applied thereto, taken in the plane of the line x, Fig. 2. Fig. 2 is a transverse section. taken in the liney y, Fig. l.

Similar letters of reference indicate like parts.

My invention consists in a novel manner of setting the cross-rails on which the slats rest, whereby they shall have a springing motion, as will be hereinafter described; and it also consists in a novel manner of setting the slats, whereby they shall have a springing motion at the points ot' their connection with the other parts of the bedstead, wherebyI obtain a very easy and sprin gy frame on which to place the bedding.

A represents the side rails of the bedsteadframe, and Al A the head and foot posts or boards of the bedstead.

B B are the transverse or end rails ot' the To adapt these rails to the purposes of my invention a mortise or suitable slot for receiving them is cut into the side rails, A, near the head and foot of the bedstead, and the ends of the rails B are cut so as to leave a projecting part or shoulder, a. Into each of these grooves a spiral spring, C', is inserted in such manner that the ends or shoulders a of the rails B will rest thereon. This arrangementenablcsthe end rails to have a free springing motion, and this constitutes one feature of my invention.

D D are the slats ot' the bedstead. To each ot' these slats,'and near each end thereof, at a point which is over the rails B B, I insert pegs or pistons E; and into the rails B B, I cut a mortise large enough to receive the body otY each pin or piston E, and at the bottom ot' this and through the rail, I bore a hole capable of permitting to Work in or through it the shanks c of the pegs E. F is a spiral spring, which is coiled around the shank ot' each pin E, one end resting against the shoulder on each pin and the other on the bottoni of the mortise. The eect of this is, that upon depressing the slats the springs will give to the slats the desired springing motion.

To 'prevent any noise which might be caused-
